From aad5837d70f8d3dc19f62f88f1434e3c9cf5ffbe Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Fri, 31 May 2024 14:24:24 +0300 Subject: utils: checkstyle.py: Show location of coding style issue within line The issue checkers display the line number and line content of each offending line, but don't show the location of the issue within a line. Improve checkstyle by adding a marker that points to the exact location.
